Performance of Aluminum PCB
1. Thermal Dissipation
Common PCB substrates, such as FR4, CEM3 are poor conductors of
thermal. If the heat of electronic equipments cannot be distributed
in time, it will result in high temperature failure of electronic
components. Aluminum substrates can solve this thermal dissipation problem.
2. Thermal Expansion
Aluminum substrate PCB can effectively solve the thermal
dissipation problem, so that the thermal expansion and contraction
problem of components on printed circuit boards with different
substances can be alleviated, which improves the durability and
reliability of whole machine and electronic equipments. In
particular, aluminum substrate can solve the SMT (surface mount
technology) thermal expansion and contraction problems.
3. Dimensional Stability
Aluminum substrate printed circuit board has apparently higher
stability than the insulating material of the printed circuit
board. When heated from 30 ° C to 140 ~ 150 ° C, the dimensional
change of aluminum substrate is only 2.5 ~ 3.0%.
4. Other Performance
Aluminum substrate printed circuit board has shielding effect, and
can alternative brittle ceramic substrate. Aluminum substrate also
helps to improve the heat resistance and physical properties and
reduce production costs and labor.
